I'd never heard of it, but after a bit of reading the Justice Party's platform and vision statements, and Mr Anderson's TV appearance, sound quite liberal/progressive - pretty much like what Bernie Sanders is saying. This US resident agrees with a lot of them.

Our friend GfS should like their statement that "GOP & Dems (are) just puppets of wealthiest US families".

Voices like these are enormously important because they force the mainstream candidates to address concerns that they would rather ignore. Not that Anderson gets any air time here - the interview we see is from Russian TV.
